Nutrition Module

Module Description 

    This module is designed as a tutorial to assist nursing students with preparation for the National Council Licensure Examination for Registered Nurses (NCLEX-RN) Computer Adaptive Testing (CAT). Students will review pertinent information related to nutrition as it pertains to the nutritional needs of clients. 
Learning Objectives

After completing this module, the learner will be able to: 

  1. Discuss dietary guidelines for specific food sources.
  2. Identify the servings in each area of the Food Pyramid.
  3. List the foods included in the dietary guidelines for each special diet. 
  4. Correlate nutritional deficiencies to specific abnormal conditions.

According to the Davis Drug Guide for Nurses, there are specific food sources that the nurse must be knowledgeable about and include in the nutritional teaching for clients. This food sources include:

These specific food sources have been identified because of their association with client conditions that are often the result of the side effects of prescribed medication or specific digestive disorders (Lactose Intolerance, Celiac Disease, Crohn's Disease, and Ulcerative Colitis).

Potassium is an intracellular cation that plays an essential role in maintaining the acid-base and water balance in the body. A proper balance between sodium, calcium, and potassium is necessary for proper cardiac function (Miller and Keane Dictionary). 

Potassium and Calcium are directly related to a healthy functioning heart. Increased or decreased levels of potassium or calcium can adversely affect the HEART with DANGEROUS ARRHYTHMIAS. 

Increased levels of POTASSIUM result in "tall-tented T waves" and decreased levels of POTASSIUM result in "ST depression and U waves".

Increased levels of CALCIUM result in "shortened QT intervals" and decreased levels of CALCIUM result in "lengthening of the QT intervals"

Calcium is the primary mineral needed for building and maintaining strong bones. Calcium is important to growing children (peak bone-building years are between the teens and early 30s) and women. Calcium helps to prevent OSTEOPOROSIS which can occur in women after menopause (Miller and Keane Dictionary). 

Sodium is the major extracellular cation and determines the osmolality of the extracellular fluid (Miller and Keane Dictionary). 

Decreased levels of serum sodium concentration are associated with diarrhea, vomiting, Syndrome of Inappropriate Antidiuretic Hormone (SIADH), the late stages of Congestive Heart Failure and Cirrhosis, Acute or Chronic Renal Failure, and DIURETIC therapy

An increased levels of serum sodium concentration are associated with insensible water loss that is not replaced  by drinking (comatose patient with Diabetes Insipidus). 

Iron is important to the human body because it is the main component of hemoglobin. A small but constant intake of iron is necessary to replace erythrocytes that are destroyed in the body (Miller and Keane Dictionary). Iron Deficiency Anemia is the most common form of anemia but loss of blood from bleeding ulcers, hemorrhoids, or injury may also result in a deficiency of iron. 

Vitamin K promotes blood clotting by increasing the synthesis of prothrombin by the liver. A deficiency of Vitamin K results in delayed clotting and results in excessive bleeding and bruising under the skin.

Vitamin D is obtained from the direct action of sunlight on the skin which changes certain substances in the body into Vitamin D. Vitamin D is required for the utilization of Calcium and Phosphorus (essential components for growth and maintenance of healthy bones). Vitamin D deficiencies result in RICKETS in children and OSTEOMALACIA and OSTEOPOROSIS in adults.
